Fast image encryption and decryption algorithms in Julia!

You are probably looking for my website, specifically, the open-source page.

I am currently based at CERN, working as a Research Software intern with the Princeton Research Computing Group and IRIS-HEP. I am an engineering senior at the University of Delhi, pursuing a major in IT and Mathematics.

I am broadly interested in {Research Software Engineering, Scientific Computing, DevOps}, {Theory of Computation, Programming Languages, Type Theory}, {Scientific Machine Learning, Computer Vision, and Machine Learning for BioMedical Data}. I am extremely passionate about Open-Source and Open-Science.

Open-Source Software

Better here.

Main software

The software I am (or I was once) involved with as a maintainer, core developer, core contributor, or was funded to work on.

pybamm-team/PyBaMM | conda-forge/pybamm-feedstock | scikit-hep/vector | conda-forge/vector-feedstock | scikit-hep/awkward | FluxML/Flux.jl | agda/agda-stdlib | pybamm-team/liionpack | pybamm-team/BattBot | smaranjitghose/DocLense | asmeurer/removestar | conda-forge/removestar-feedstock

Significant contributions

Significant voluntary contributions or spin-off projects (was not directly funded to work on them but my work expanded and encompassed them).

FluxML ecosystem | Scikit-HEP ecosystem | luluxvi/DeepXDE | zarr-developers/zarr-python | scientific-python/cookie | CoffeaTeam/coffea

Small but nice contributions

Small contributions (not a spam spelling fix in README) that I did spend some time on.

Add more documentation

Description

Current documentation has only API documentation. Add more documentation and link the jupyter notebook examples.

Create a table of results in the README file

Description

Right now the results look bland, add a table that looks something like this -

Results

S. No.	Original Image	Image Dimensions	Encrypted Image	Decrypted Image	PRNG used	Algorithm used
1	x	(512, 512)	y	z	Logistic Map (logistic_key)	Substitution (substitution_encryption, substitution_decryption)

Motivation

Would look good

Possible Implementation

Vectorize substitution algorithm's functions

Description

Vectorize both the functions using the . operator to fasten the execution.

Motivation

Fast encryption and decryption!

Possible Implementation

No response

Additional context

No response

Create examples

Separate out examples from the docstrings into a new examples folder. Maybe try out Pluto.jl for julia notebooks!

Allow users to pass image rather than path

In both the substitution methods.

Add docstring for the module

Description

Right now the documentation for the module as a whole is missing. This should be added.

Use pre-allocation

ChaoticEncryption.jl Version

0.1.1

Julia Version

1.7.2

Describe the bug

The push! function is slower in comparison to pre-allocating the array and replacing its element -

ChaoticEncryption.jl/src/logistic_key.jl

Lines 57 to 64 in c484c6c

	keys = Vector{Int64}()
	x = x_init
	for i = 1:num_keys
	x = r * x * (1 - x)
	key = x * scaling_factor % upper_bound
	push!(keys, trunc(Int, key))
	end

[Bug]: Failing doctests (passing as warning right now)

ChaoticEncryption.jl Version

dev

Julia Version

1.7.1

Describe the bug

Look at the documentation workflow. The tests are failing (are passing as warning intentionally) because of a type mismatch.

REGISTER!

@JuliaRegistrator register

Remove redundant dependencies

Description

I think a lot of deps are not being used, remove them.

Motivation

Redundant code

Possible Implementation

No response

Additional context

No response

Migrate to the latest julia version

Description

Migrate the code, examples, and documentation to Julia 1.7.2

Motivation

The failing doctests might pass, plus good to be on the latest Julia version as our CI runs on the same.

Possible Implementation

Write equation in `LaTex` in deployed documentation

Add shuffle encryption

Add CI to clean gh-pages

Add benchmarks

Description

Using Julia gives us the advantage of speed, hence adding some benchmarks would make sure that the speed doesn't go low. Add some benchmarks and also a new workflow to benchmark periodically and on a PR.

Motivation

The package should be fast, given that it is operating on 1000s of pixels.

Possible Implementation

BenchmarkTools.jl

Add more results in README

Description

Add more results by combining different images, dimensions, PRNGs etc.

Update README

Add examples for `!` methods

Description

The documentation right now lacks examples for encrypting and decrypting images in-place. Add a small section showing the same.
